Abstract (en)
An oil pump system for a vehicle includes: a vane pump (2) having a plurality of vanes which respectively project retractably from a plurality of vane accommodating grooves provided in a rotor so as to be brought into sliding contact with a cam surface, the vane pump (2) being adapted to supply a hydraulic fluid to an automatic transmission (51); an electric power-driven oil pump (12) for assisting the hydraulic pressure of the hydraulic fluid during an idling stop of the automobile; and an ECU (4) for controlling its operation. During an idling stop, the hydraulic fluid is fed to the automatic transmission (51) by the operation of the electric power-driven oil pump (12) to assist the hydraulic pressure, while the hydraulic fluid is fed with pressure also to the vane accommodating grooves to press the vanes against the cam surface.
